TIME-CONTROLLED MECHANISM roe emmo ms. 7.

To all it may concern:

Be it knownv that I, JAMES Core, a'subject of the King of Italy, residing at Ranecting rods or elements, connected withthe operatingparts of the clock, and extending to convenient positionsexteriorly of the casing of the graphophone. I j

A further ob 'ect of the invention is to so correlate the time. controlled mechanism and the operating parts of the graphophone, that the elements ,thereof cooperate in a novel manner, producinga construction which is simple, inexpensive and easy to operate.

InQorder' that access may be readily"hadto the'bolts 22,-f0r turning them, and tofthe .clock' 'casffing,,to remove it, or to adjust the clock,the- Fig. 2is an enlarged plan v ew of the stop side of the casing 10 at a-right angle toQthe regulate the volume of sound passing from adial 28, provided with characters fo r in operation at a selected time, as isweu known The alarm -mfeansen1bodies the usual spring-winding key 32, which is 170- tELtGdiT-LOIIQ direction to wind up the spring i and turns in an opposite direction when-the alarmmechan1sm is operating or'i unwinding. The key 32 embodies apertured ears and an 'ext'ension 34, projecting out V l r or the like. A table 37 is pivoted 'upon the wardly beyond the same, such extension serving as a drum, upon which a flexible ele ment, to be described, is wound. By the term alarm mechanism, is meant the usual spring operated means found in the ordinary alarm clock,foroperating-an alarm at base 35, as shown at 38, and carries an inner arm 39, provlded w th a socket 40, receivlng "fibrous material 41, to contactwith the edge or periphery of the rotatable table 14. The

- table 37 .carries an outer arm 42, the outer end of which is preferably bent upwardly, while the arm 39 is preferably straight. The upwardly offset portion 43 of the arm 42 is arranged in the plane above the arm 39. The base .35 has an extension 44, having connection with a retractile coil spring 45, secured to an ear 46, carried by the arm 42.

'When the lever 39 is shifted to the inner position to holdthe rotatable table against movement, the spring 45 is shifted to the a right of the pivot 38, or past dead center,

and. hencewill hold the'br'ake element in the said position. When the brake element is swung in the direction of the arrow, for a slight distance, the spring 45 is shifted upon the opposite side of the pivot 38, and. quickly l completes the shifting movement of the brake element, and retains it open.

' ed to be started inits shifting movement by Thearm 42 of the brake element is avertically adjustablepin 47. (see Fig. 4)

which is arranged behind this lever when the brake element is set, as shown in Fig. .1.

The pin;47. is screw-threaded and engages 1 formedupon a reciprocatory rod 49. The

pin47 travels in a slot 50. The pin 47 may V also serve as a stop for thearm 39, when the a K position.

brake element is being swung to the open The rod49i's arranged beneath the men and slides within apertured brackets 51, se-

a v cured t e thetop. The rod 49 is shifted forwardl'yin the direction of the arrow, a

hook 59, to detachably engage within either ear 33. 7

The operation of the apparatus is as follows: M

WVith the clock in place, the operatormay pass his hand through the open side ofthe casing, and connectthe hook 59 in the ear 53. The key-32 is now turned to wind up the spring of the alarm mechanism, which at the same time winds thecable upon the element 34; This winding of the cable draws the rod 49 r'earwardly, and places spring 52 under tension; The pin 47 may now be in the ole "vated position, and the brake element may now be-swungftothe closed' position, for

holding the table against rotation. the

willflrotate thekey 32inan opposite direction to unwind the 'cable' 54, the spring 52 then shifting the rod 49tothe left, Fig. 4.

LThe'pin 47 will Contact with the arm 42, and [swing the brake element to the open or'release position, whereby the spring motor will rotate the table 14. jThe pin 47. being in advance of thearm 39, will function 'as a stop for the arm, upon its outward movement. Should it be desired tousethebrake roper time, the time controlledmechanism element, independently, of the time controlled means, the pinj47 is rotated to flower it,beneath the upwardly oifsetendf43 of the arm 42, but this pin will still serve as'a stop for arm 39., The brake element may now be turned to the left, and'employedto hold the 1 table against rotation, and manually operate'd, to release it, as maybe desired. V p It is to be understood that the form of my ,invention herewith: shown and described is to be taken asja-preferredexample of the same, andthat variouslchangesin the. shape,
